Your well may be low or you may have a crack in your pipe so when it is off water can drain down in the pipe and then it will pump all that air back into the system. To check this you will need to pull the pump and depending on how deep your well is this can be a job. Also you will need a tool to get into the housing to break it free and start it pulling. This consists of a long pipe threaded to fit into the fitting inside the caseing. If you have never done this you may want to hire a pro the first time to see how it is done. Good luck.
